A hot spring inn renowned for its variety of baths and its Nano water cold plunge bath
Kagoshima Ibusuki City
Ibusuki Kokoro no Yu is a popular day-use hot spring facility in the Ibusuki Onsen area that also offers accommodation. The main bathing area features a variety of baths, including indoor baths, open-air baths, and a carbonated hinoki cypress bath. The facility has two types of saunas: a spacious five-tier Tower Sauna and a Steam Sauna that combines hot spring steam with a foot bath. The cold plunge bath uses gentle Nano water, similar to a lotion, set very cold for an intensely refreshing experience. The outdoor relaxation area provides many chairs so you can enjoy a supreme totonou (a state of perfect relaxation) while feeling the tropical breeze.
TypeNatural Hot Spring
A sodium chloride spring with strong moisturizing properties. Because Nano water is used, it penetrates the skin easily and can be expected to have beautifying effects. Enjoy the hot spring across more than six different types of baths, including open-air baths, reclining baths, seated baths, plain hot baths, and lukewarm baths.
Sauna TypeDry Sauna
Stove TypeInfrared Heater
Capacity20people
